The purpose of this study was to analyze the recognition of those majoring Library & Information Science on the jobs that they can get and want to work for, employment requirements and their preparation, to identify problems and to suggest how to improve current status. To this end, the jobs and employment rate reported by most of the Depts. of Library & Information Science and the preferred jobs and preparation to those majoring library and information were surveyed with 107 students studying in the Dept. of Library & Information Science in the K University as the subjects. According to the results, 49 jobs were identified as the jobs that those majoring Library & Information Science could get into. In the 1st to 20th job ranking groups, 82.1% of all identified jobs, librarian job took lower ranking as 29.2% while other jobs accounted for 52.9%. However, among the jobs from the 1st to 20th ranking accounting for 96% of all jobs that the subjects wanted to have, the librarian job took 45.8% and other jobs 50.6%, which suggested that the preference on librarian job was slightly increased among the jobs that the subjects wanted to have. Furthermore, the employment requirements were classified into religion, language, scholastic achievement, certification and experience. In accordance with investigation on requirements from employment announcement, 92% were in the generally acceptable level or insufficient level. On the basis of such results, it is suggested to introduce a variety of jobs to students and to provide Case-by-Case employment guidance for improvement of employment rate and social capability of students.

In this paper, we consider the minimization of the total weighted earliness-tardiness penalty of jobs, regarding the partial precedences between jobs. We present an optimal scheduling algorithm in O(n(n+m log m)) where n is the number of jobs and m is the number of partial precedences. In the algorithm, the optimal schedule is constructed iteratively by considering each group of contiguous jobs as a block that is represented by a tree.

This is a case study of corporate culture marketing to commemorate the 10th anniversary of the death of Steve Jobs on October 5, 2021. Corporate culture marketing seeks to derive cultural consumer values through Steve Jobs' fandom, and to increase corporate brand image and achieve profits. According to Big Data, Steve Jobs' brand image was derived from 'Innovation', 'First', 'Creativity', 'Change', and 'Design'. So, the relationship between Spigen convergence culture space 'SpigenHall', which is highly related to Steve Jobs' brand image, and the opera , which is made of the material of former Apple CEO Steve Jobs, is analyzed with big data and culture. We investigated the opinions of content experts. SpigenKorea and the digital opera are designed to provide Steve Jobs' story of joy and sorrow, offer VIP members' premium services, press publicity is 'the first in Korea', GangNam's suitable for famous celebrity performance venues and cultural and artistic venues 'SpigenHall', the revenue of the performance ticket was selected as a donation. This study is suitable for researching the life story of male CEOs and planning a cultural city. The limitations of the study need to analyze various works by genre and attempt to analyze consumer values according to the industry.

In this study, we expected the perceived difference of job calling and decent jobs between recent generation and baby-boomer and eco baby-boomer generation. Understanding perceptions of jobs by current generation that are perceived as lifetime jobs rather than lifetime workplace will make some valuable contributions to future job research and policy. The aim of the study was to examine the subjective perception of decent jobs among university students who are ready to go to labor market. By using Q methodology, we extracted 291 Q statements and 47 Q samples. In addition, 31 subjects classified Q samples into Q distributed tables. We used Ken-Q Analysis program. In the results, we found five types of perceived subjectiveness on the decent jobs, which were interests-seeking, balance-seeking, toward organization, power-seeking, and career development. These results confirm the diversity of perceptions of decent jobs. Then, we suggested policy implications to help the labor market entry based on the results.

This paper considers the nonidentical parallel machine scheduling problem in which n jobs having different due dates are to be scheduled on m nonidentical parallel machines. For the make-to-order manufacturing environment, the objective is to minimize the number of tardy jobs. A 0-1 nonlinear programming model is formulated and a heuristic algorithm that allocates and sequences jobs to machines is developed. The proposed algorithm makes use of the concept of assignment problem based on the suitability measure as the cost coefficient. Computational experiments show that the proposed algorithm is superior to the existing one in some performance measures such as number of tardy jobs. In addition, this algorithm is appropriate for solving real industrial problems efficiently.

The cost-effective reduction of occupational radiation exposure (ORE) dose at a nuclear power plant could not be achieved without going through an extensive analysis of accumulated ORE dose data of existing plants. It is necessary to identify what are high ORE jobs for ALARA implementation. In this study, the Rank Sum Method (RSM) is used in identifying high ORE jobs. As a case study, the database of ORE-related maintenance and repair jobs for Kori Units 3 and 4 is used for assessment, and top twenty high ORE jobs are identified. The results are also verified and validated using the Friedman test, and RSM is found to be a very efficient way of analyzing the data.

In an earlier paper ('Scheduling Jobs on a Number of Identical Machines' by Elmaghraby and Park, March 1974, AIIE Transactions) a branch-and-bound algorithm was developed for the sequencing problem when all jobs are available to process at time zero and are independet (i.e., there are not a priori precedence relationships among jobs.). However, the amount of computation required by the algorithm was not considered to be short if more than 50 jobs were processed. As an effort to improve the algorithm, the present paper modifies the implicit enumeration procedure in the algorithm so that moderately large problems can be treated with what appears to be a short computational time. Mainly this paper is concerned with improving the lower bound in the implicit enumeration procedure. The computational experiences with this new branch-and-bound algorithm are given.

In parallel job scheduling, each job can be executed simultaneously on multiple machines at a time. Thus in the input instance, a job $J_i$ requires the number $m_i$ of machines on which it shall be processed. The algorithm should determine not only the execution order of jobs but also the machines on which the jobs are executed. In this paper, when the jobs have deadlines, the problem is to maximize the total work of jobs which is completed by their deadlines. The problem is known to be strongly NP-hard [5] and we investigate the approximation algorithms for the problem. We consider a model in which the algorithm can have more machines than the adversary. With this advantage, the problem is how good solution the algorithm can produce against the optimal algorithm.

This paper analyzes job creation when the Korean economy transitioned to a knowledge economy from the 1990s to the 2010s. During this period, the ratio of service to manufacturing jobs increased, knowledge intensive industries grew, and job creation became geographically concentrated around Seoul. The changes slowed down in the 2010s, and overall job growth weakened. To analyze the effect of job creation driver industries during this period, the main part of which are knowledge intensive tradable service industries, on local service job creation, I use a modified version of the local labor market of Moretti (2010). I analyze the job changes during 1995-2005 and during 2006-2016 in 237 Si-Gun-Gu areas in the Census on Establishments datasets. I find that one manufacturing job creates 0.5 local service jobs and that one tradable service job creates 1.1 jobs within Gu areas of metro cities and 2.3 jobs in Si-Gun areas. The job creation relationship between the tradable and local service sectors was not altered in this period. As more jobs were created in the tradable sector driven by the transition to a knowledge economy, job creation overall remained active, with the opposite also being true.

For developing the Group Health Care System, health managers' job structure were analysed in the aspects of content, amount, and process. As a trial research, data were collected by a standardized job analysis table to 6 doctors, 40 nurses, and 11 industrial hygienists of Group Health Care System. Health care managers were performing complex and intellectual jobs such as healh education for workers, managing health care, conference as well as more simple jobs like as filling diary. Especially, job was consisted of general job and health care management job in the proportion of 1:2.18. The major general job were data management related with the health statistics, and major health care management jobs were managing health care, health counselling, environmental management of working sites. Each specific jobs were required differentiated intellectual capacity, creativity, autonomy, psychic stress, and physical work; most respondents perceived that health care management jobs should require more inputs than general jobs. Additionally job satisfaction and perceived need on specific Job items were anzlysed. Results of this research, suggested through the field experiences in working sites, should be considered for improving the Group Health Care System.
